Specification of Letters Patent.

Appli'catimi filed January 13,1-91'5; Serial no. 1 ,992".

To of whom it may concern:

Be it known thatI, BOUKA DE Born, a itizen of the United States, and aresident of Corsica, in the" county of Douglas and State of SouthDakota, have inventeda new and Improved (ham-Spout 'Aldjuste'r, of whichthe following is a full, clear, and exact description.

'l ris invention relates to improvements in adjusting means for grainchutes or spouts, and has for an object to provide an iinproved-'const'ruction adapted to be used in any place, especially on a thresherwhereby the dischargin chute may be moved to any desired position andlocked in said position;

Another object in view is to provide an adjusting means for a grainch'utewhich may be swung around a suitable pivot and locked at any pointwithin its movement.

A- furth'er object of the invention is to provide a locking device forlocking a grain chute in any osition and means co-aeting therewith forraising and lowering the discharge end of the chute. i g

In the accompanying drawings-Figure 1 i is air enlarged detailedfragmentary side view of part of an elevator grain chute and mechanismembodying the invention; Fig. 2 is an enlarged detailed fragmentary sideview of means for raising and lowering the discharge end'of the chute;Fig. 3 is a section through Fig. 2 approximately on line 3-3; Fig. isa'sectional view through Fig. 2' on line Fig. 5' is an enlarged side viewof the locking mechanism and associated parts embodying certain featuresof the invention; Fig. 6 is a top' plan View of the struct'i'ire shownin Fig. 5; Fig. 7 is" fragmentary sectional view on line 77 of Fig. 5.

Referring to the accompanying drawings by numerals, 1 indicates part ofa threshing machine and 2 an elevator of any desired kind. Pivotallyconnected near the top of the elevator 2 is a grainspout or chute 3 ofsubstantially any desired kind, which spout or chute is provided with avalve or shutoff 4!. near the lower end. It will be evident that theelevator and chute could be associated with other devices in addition toa threshing machine, as for instance an ordi nary grain bin. However,when using a threshing machine it is designed to have the samecontinuously operate and therefore continuously discharge graintherefrom. In order that the continuously discharged grain may be loadedinto diilerent sacks; or other suitable receptacles in small quantities,it is necessary to move the chute or spout 3 on its pivotal liie'aring5' which may be of any desired kind; Asthe discharge will not instantlyfilt the sack or bag it is necessary to hold the spoutor chute 3stationary for an appreciable time in order that the sack or receptaclemay be filled. To obviate the necessity of'empl oying a personcontinually for holding the spout in proper position, means have beenprovided for locking the spout quickly in any desired position. The gateor valve 4 is used for temporarily shutting oi? the grain while thechute is being moved from one position to another.

As shown in Figs. 1, 5 and 6, a semi-circul ar rack o is provided whichis bolted or otherwise rigidly secured to the elevator 2,

and which is provided with a flange 7 having spaced notches 8 which formthe rack and" which are adapted to receive the" legs 9 and 10 of apivotally mounted frame 11. The pivotally mounted frame 11 is pivotallymounted on the'bra cl'ret 1 2 which is clamped by a suitable bolt to thebracing beam 13.

The bracing beam 13 is provided with an eyelet 14 interlocking with theeyelet 15, which eyelet is pivotally connected with a bracket 16 rivetedor otherwise rigidly secured to the elevator 2. The frame 11 isprovided'with an upwardly extending arm 17 to which one end of spring 18is connected, the opposite end of spring 18 being con-. nected with astop or eyelet 19 secured to the beam 15. Spring 18 is a retractilespring and tends to continually hold the legs 9 and IOin engagement withthe. notches 8 of the rack (i and thereby prevent a swinging of thebracing beam 15 and th'e chute 3* with which it is connected. The outerend of beanr 15- is provided with a tongue 20 (Fig. 3 and'a pairofbearingsides 21 and 22'which rest upon-the lower surface of the flanges23' and 2 k of'tlie guide 25, while the tongue 20 fitsd nto theg-iioove-26'oftheguide 25. The outer end of the beam 13 is provided witha lock or eyelet 27 .u hich"ieceivesthe cable 28,

' said cable 28'passing over a pulley 29 and rying tongue 20 is raisedto the desired extent. A reverse movement of the various parts will ofcourse allow a lowering of the end of the chute or spout 3. Usually thespout or chute 3 is adjusted to a certain height before the grain isallowed to be discharged therefrom and is left in that adjustment for anindefinite time while the chute is swung back and forth as occasion maydemand.

In order to allow a person near the lower end of the chute or spout 3 toquickly move the spout a pivotally mounted arm or crank 31 is arrangedon the spout 3 to which isconnected a cable 32. Cable 32 passes overpulley 38 mounted on the outer end of beam 15 and has the inner endconnected with the lower part of frame 11 so that when the crank orlever 31 is moved upwardly or away from the spout 3 frame 11 will bemoved pivotally out of engagement with rack 6, whereupon the spout orchute 3 may be moved to the desired position after which the crank 31 isreleased and frame 11 will automatically engage the rack 6 under theaction of spring 18. The cable 32 may be of any desired structure butusually adjacent the frame ll, the same being formed as a chain so thatany of the links may be caught or hooked over the hooked member arrangedat the lower endof the frame 11, whereby the slack in the cable may betaken up easily.

In operation the parts are adjusted, for instance, substantially asshown in Fig. 1,

and when it is desired to move the chute to one side so as to dischargeto another receptacle crank or lever 31 is raised and frame 11 moved outof engagement with rack 6. The chute or spout is then manually swung toone side after which crank 31 is released which will allow spring 18, tocause legs 9 and 10 of frame 11 to engage rack 6. This will lock thechute against any further swinging movement. If for any reason it isdesired to raise or lower the chute cable 28 is actuated so as to raiseor lower the outer end of bracing beam 15.

What I claim is- 1. In a device of the character described, thecombination with a pivotally mounted grain chute, of a guiding trackarranged thereon, said track being formed with a groove, a pivotallymounted bracing beam having a nose fitting into said groove, means forsupporting the outer end of said beam, said means being used to raisethe outer end of said beam for adjusting the height of the outer end ofthe chute, and a locking member connected with said beam and with thechute for locking the beam and chute against a horizontal swingingmovement.

2. In a device of the character described, the combination with a chute,of a pivotally mounted bracing beam for supporting the outer end of thechute, means for locking said bracing beam and the chute in any desiredposition and against horizontal swinging movement, said means includinga stationary rack, a member acting as a catch pivotally mounted on thebeam, and adapted to engage said rack, and an operating member extendingto a position adjacent the lower end of the chute.

3. In a device of the character described, the combination with aswinging chute, of means for locking the same in any adjusted position,said means comprising a bracing bar, a rack formed with a plurality ofnotches, a swinging catch member pivotally mounted on said bracing barand formed with a pair of arms adapted to fit into said notches when thesame is in a locked position, a spring acting on said catch member forcausing the same to normally engage said rack, and manually operatedmeans extending to a position near the lower end of said chute forreleasing said catch member temporarily.

I. In a device of the character described, the combination with aswinging chute, of means for locking the chute in any adjusted position,said means comprising a bar for supporting the lower end of the chute, apivotally mounted catch arranged on said bar, a spring for urging saidcatch in one direction, a stationary rack adapted to be engaged by saidcatch whereby the catch and the bar cannot move, and a cable extendingfrom .said catch to a point near the lower end of said chute, said cablebeing adapted to be manually operated for releasing said catch when itis desired to swing said chute.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. 1
